rior of the dome 5.,' andat their lower endsl with lthe interior of the tank 1. A gas chamber 7 is located in the receiver l and communicates with the interior of the dome 5. The said receiver l contains water in the usual manner which elt'ects a seal about the lower edge of the dome 5. A service pipe `is connected at one end with the lower portion of the gas chamber 7 and passes out of the-side 'of the machine as illustrated in Fig. 1 of the drawings. A by-pass 2 is connected at one end with 'the serv-ice pipe 6 and i.is pro- `vided yvitli al valve 3. 'The stem of lthe said 'valve 3 is provided with a lever 4'., to one end of which is attilehedwa weight .-5, .b
